Hey guys, Stephanie with AmericanMuscle.com, here with my quick overview of the Ford Racing EV6 47 Pound High Flow Fuel Injectors that are available for all 1999 and up GT Mustangs. The EV6 47 Pound Injectors from Ford Racing are going to be for the Mustang owners out there who are looking for a little bit of an upgraded injector to support a build. So these injectors will plug right into a range of Mustangs, which means it can be used in a few different motors. So the specific power mods that they can support will differ depending on the motor. A 47-pound injector isn't a huge upgrade at the end of the day, so these are going to be for the more mild and not off-the-wall builds.
So how much power can 47-pound injector support? There's not really a straight, cut and dry answer for that, but I can tell you that these injectors can support an NA build, or naturally aspirated build, of around 600 to 650 horsepower, which will put them at an 85% duty cycle, assuming that you're running slightly over 39 PSI fuel pressure. The injectors are not going to be able to support as much power on a forced induction setup because you have that greater amount of air, so you're looking at these delivering enough fuel of just shy of 500 horsepower, assuming the same 85% duty cycle and 39 PSI fuel pressure.
So 500 horsepower for the Ford 6 Motor is going to require different things than 500 horsepower from a Coyote motor, so you have to take that into consideration. Numbers I gave aren't the end-all and be-all. I'm just trying to give you guys an idea of what the injectors can support. Obviously, your complete setup and your tuner are going to come into play, and if you can bump up your fuel pressure, if your pump can support that, that is, these injectors will be able to support a little bi more horsepower.
There is a note on the site that cautions that these are not recommended for forced induction builds on '05 to '10 Mustangs, and that goes back to what I said earlier about the max power that these can support on a turbo or supercharged build. You get to 500 a lot faster on the newer mod motors, so just be mindful of the restrictions when you're shopping for fuel injectors. So low boost applications can probably get away with it if you've got a good fuel pump and you want to run a higher duty cycle, but I would recommend a different injector because I'd hate to see you guys limited by your injector when you go for your tune.
Since the EV6 47 pounders are actually one of the smallest injector upgrades, you also have to consider the fuel that you'd like to run with your build. This injector will work with all different types of fuel, whether it's pump gas, E85, or race gas, but once again just be mindful of the power limitations. You're looking to do full bolt-ons on a new Coyote and to run E85, these aren't going to make the cut for you.
When it comes to price, you can expect to spend just under $300 for this set of injectors, which is actually quite affordable. Obviously, as you go up the ladder and hit those larger flowing injectors, things are going to get more costly, but all Ford racing injectors are held to the same OE specs that are used in all Ford vehicles, while some competitors out there do not build to OE standards and their injectors are not held to any specific build tolerances.
These injectors are an EV6 body style injector and they have a US car style injector, which makes them plug and play for most setups. Overall, it's a very simple install here, guys. You're just looking at clips at the end of the day, but you are playing with fuel, so I'd just make sure that you have a handful of shop rags to keep things contained. It's nothing crazy here, so I'm going to call it a one out of three on the overall scale of difficulty, but obviously injectors are not one of those things that you can just plug and go so you will need to tune for them in order for the car to operate properly. So just keep that in mind before installing.
The install will be slightly different depending on what gen Mustang you have, but it all comes down to releasing any fuel that's in the rails, possibly by pushing a Schrader valve and collecting it in a rag. When you unbolt the fuel rail, obviously you've got to remove anything that might be in the way and remove the fuel rail from the manifold. You may get lucky and have all of the injectors come off with the rail, or there may be some still in the manifold that you need to get out. Just make sure to get all of the old o-rings out before installing the new injectors.
You can install your new injectors in the fuel rail, and just make sure they seat properly in the rails and the intake before you tighten the fuel rail back down. Once you're done under the hood, I would turn the key to the on position, but don't start the car yet. You're just priming the fuel pump and cycling some fuel to get some pressure into the system again. I would do this a few times and then check all of the injectors for leaks, and the lines, too. So assuming that you have the tune all figured out, after all that's done you can start it after and check for any leaks.
So to wrap things up with the Ford Racing EV6 47 Pound High Flow Fuel Injectors, these are a mild upgrade in the world of fuel injectors that can support around 650 NA horsepower or 500 forced induction horsepower. They're very easy to install and they're not going to break the bank, either. As always, I suggest you check them out more online for yourself, and for all things Mustang, keep it right here at AmericanMuscle.com.

5 Top Rated Questions

mpgs Will these affect fuel economy?

Fuel economy isn't really a topic with injectors. You don't change injectors to effect your fuel economy, in other words.
At its most basic, a fuel injector is like a squirt-gun. The bigger the squirt-gun, the more that can come out at any given squeeze (impulse). Finding the right balance is a question of demand, and your speed shop tuner can help you figure out what's the best match.
Here's a rough guideline: (F x 8 x 0.8) / 0.5 = P
F = the size of the injector
P = the amount of horsepower the setup can support
So we'd take 47 (for the 47lb injectors on this page) times 8 (for the number of cylinders) times 0.8 (the best efficiency is around 80%) and divide that all by 0.5 (which is the Brake Specific Fuel Consumption, around 0.5 for a n/a engine, 0.6 for a boosted engine).
So you get (47 x 8 x 0.8) / 0.5 = 600HP (roughly)

If I wanted to switch over to e85 would I only need these fuel injectors? Or did I need something else too?

Hello! Along with the Ford Performance EV6 High Flow Fuel Injectors, it is recommended to upgrade your fuel lines, fuel rails, and fuel pump if you have a pre 2010. Anything from 2011 to present will just need 47 lb injectors and a new tune!

Will these 47lb injectors fit a 2015 GT? That question has been asked previously in the list of questions but it is misleading as the individual from AM said "no" although years 15-17 are listed as compatible.

The Ford Performance 47lb injectors will work with the 15-17 models just fine yes!

That is a perfect question for Bama. When it comes to fuel injectors, if you are changing them at all, your tuner needs to make that decision as they determine what fuel components are needed relative to the tunes they write for you. So I supposed it is possible, but I would speak with them and see what they suggest.

For those modifications, the stock injectors would be sufficient. If you are contemplating further modifications down the road, a new set of injectors may be something that we would be recommended depending on those modifications.

A 47Lb hr injector will not improve performance unless you have far exceeded the capabilities of your stock injectors. Please contact our Customer Service Department so we may discuss your setup and determine if larger injectors are required.

Injectors arrived as scheduled. The package was not as expected a box inside another package without any support. But the worst part was when I opened the package that contained the injectors, they had no caps at either end and they were loose in their location. I am debating on returning them or take them to injectors shop for inspection.

I bought these Lu47's because I decided to make the switch to E85 in my S550. Right now I'm at the crossroads of deciding exactly what I want to do with the car, so I kept it simple by purchasing a couple minor bolt-ons and a tune. These could carry me through a light, modest NA build, or I'll have to dump them later on if I decide to go for big power. Given the price point, I felt like it was worth a little piece of mind to just throw these in for now. Combined with the tune, I truly believe it woke the car up. Install was about as simple as it could possibly be; disconnect what you need to disconnect, unbolt what you need to unbolt, pop the rail off and replace the injectors. If you're just keeping it simple and modest for the time being, I recommend grabbing this set injectors.
Fit: Could not have fit better in to the rail. Let the C-Clips orientate them, reinstall into the vehicle and plug the connectors right in.
Performance: Considering this is more of supporting modification, I didn't want to rate this at 5 stars. Like I mentioned, if you are keeping it simple, these are adequate injectors. If you have the money and you know that you more than likely will go for big power, then get a better injector. Keep in mind what your time frame is, what your budget is, and what your goals are.

Adding to previous mods, you can really feel the additions, like these injectors. Wow, I can feel the response and torque at all rpm ranges. Now to add the heat range 7 plug and sr 4v coils, and my NA build will be done.

This install took me 10min. It’s very straight forward and easy to replace the injectors. A little tip is you can use two hands to slid off the clips and you can do it quickly. Just make sure to take your fuel pump fuse out and try to crank the car to take the pressure out of the system. I noticed a big gain going to E-85. Thanks a lot AM!!!
